Borda Count voting system (Executive summary)

Borda system:
Each vote is an ordering of the N candidates from best to worst.
(Voters are not allowed to omit a candidate they know nothing about, and are
not allowed to regard two candidates as equal.)
The top ranked candidate gets a score of N-1, the bottom ranked 0, and more generally the
Kth-ranked gets a score of N-K. All scores are summed and the candidate with the
highest total score wins.
